When the government actively decides the price of goods and services, it becomes more and more like communism. The government should instead uphold the free market and proactively prevent collusion and monopolies that threaten the free market, this is harder to do in the US because of lobbying though.

Ok.
Can we get to what this kind of law is actually doing? The simplest version would be roughly "stores need to display prices and only change them once per day". No specific prices are being imposed.
Slogans and bromides are good starting points but not solutions.
The government IS preventing coordinated price setting by closing the loophole of third party data brokers.
